ABSTRACT
In this article we present an approach for a precise segmentation of
spherical particles in transmitted light image stacks. A main goal
was its fast operation and a high robustness to occlusions and ag-
glomerations of the particles. The system is based on a voting proce-
dure that finds the centers and radii of the particles and a subsequent
precise segmentation with an active contour approach. To meet the
demands of an online pollenmonitor for high speed and low mem-
ory consumption a multi-scale approach was applied. The proposed
techniques successfully segmented the pollen grains in a vast amount
